NC750x 2016 replace classic halogen headlight to 2018's LED lamp

[Marcin NC750XD 6]

Hi, I recently bought an used NC750 2018 LED head lamp to replace a halogen one on my bike. I already found the wiring diagram of 2018 version and know what wires are in the plug, but I can't find the connector's exact pin-out anywhere on the net. Can anyone provide me a photo of the wires and the plug or at least write me what color goes to which pin?

WTF would you want to?

 

The NC LED headlight is utterly hopeless. It's like trying to use a laser pointer to find where you dropped your keys in a darkened football stadium.

 

Stick with the H4.

 

Welcome to the forum BTW 😁

What he says; I’d stick to the H4, unless you want up-to-the-minute technology and no effective front lighting. Easily the most useless lights on 30+ bikes. Not sure you can retrofit  anyway.

If you want a brighter light, get an HID conversion from a reputable British supplier. You should get a beam pattern that passes the MOT. (Some cheap Chinese versions are hit and miss as Quality Control is dodgy.) For a short time the MOT regs were changed to make them a fail but eventually they saw sense. So much better than the NC LED light and standard Halogen.

+1 stick with the H4 plus decent bulbs, LED are bright but way too narrow a beam

Thanks guys, but I don't ask for an opinion here. I have two additional lamps which are bright enough (2x H7 halogen) so the main headlamp is used as a DRL during a daytime only and the LED one acts much better in this role.

If it helps you sort out the wiring and power requirements, you can pay per view the workshop manual from Honda. It might help you find out where it’s a straight one for one swap or needs a suitable LED driver unit. Never had an LED NC, only a H4 one, but have done some electrical mods for people. The wiring is different, but I’m not aware of the detail.

OK. I figured it out by myself using an universal meter and a car 12V battery. Here is the pinout of the NC750x LED headlamp connector in case somebody will be doing the same mod:

 

 

The image shows the back of the lamp and the connector placed there from the driver's point of view (bottom of the image is a bottom of the lamp). Black pins are N/C, the rest is as described on the picture. The DIMMER Switch pin works like this: when connected to GND switches to high beam, when not connected -> low beam. METER indicator gives +5V DC when switched to high beam (connected DIM SW to GND)

 

And here are the connector's wire colors from the NC's electric schema:
